cmdVcpuPin: Remove dead code

There's this condition:

flags & VIR_DOMAIN_AFFECT_CURRENT && virDomainIsActive(dom)

which can never be true since VIR_DOMAIN_AFFECT_CURRENT has hardcoded
value of zero. Therefore virDomainIsActive() is a dead code. However,
the condition could make sense if it is rewritten as the following:

!(flags & VIR_DOMAIN_AFFECT_CONFIG) && virDomainIsActive(dom)
